This is my most advanced work to date. Whole lot of programming.
I think it would be interesting for you to explore it's features: photo galleries, video hotspot controls, nice hotspot styling, modal html window.
The tour is quite messy at startup by showing thumbs and automatically playing video. Also quite big hotspot font size and opening thumbs by hover were customer's wish.
It would be nice to read your UX impressions.
